Spatio-temporal perturbation of the dynamics of the ferroin catalyzed Belousov-Zhabotinsky reaction in a batch reactor caused by sodium dodecyl sulfate micelles.

摘要: The effects of the anionic surfactant sodium dodecyl sulfate (SDS) on spatio-temporal and temporal dynamics ferroin-catalyzed Belousov−Zhabotinsky (BZ) reaction have been studied over a wide concentration range. For first time, investigations were performed also for unstirred systems. presence SDS in mixture influences oscillatory parameters to an extent that significantly depends concentration. trend wave speed v upon increasing amount was found maximum at [SDS] = 0.075 mol dm−3 (v 0.071 mm s−1), after which decreased 0.043 s−1 0.5 dm−3, is below value absence 0.055 s−1). response BZ system addition has ascribed two different causes: (a) peculiar capability organized assemblies affect reactivity by selectively sequestering some key reacting species ...
